"I went 30 minutes after it happened," she says. "Me and my dad rushed over there. We saw that there was nothing there. We got out of the car and started walking, (amid) downed power lines and everything, just looking through the trash, yelling for them, yelling their names, to see if anyone would respond. But no one did."

Twenty-year-old Moriah Brough, her boyfriend, 21-year-old Joseph Babcock, and their children, 2-year-old Jaydon and 2-month-old Kendall, were killed when the tornado ripped through the town. Angel Babcock, a little more than a year old, was the only survivor. She was found alone in a field, alive -- but she'd suffered critical brain injuries and died Sunday afternoon.

An emotional Kendra Brough said, "Moriah, my sister, she was a really good mom. She only wanted the best for her children. They didn't have much, but she tried hard to provide. "

Brough and her extended family have received an outpouring of support.

And across the devastated region, strangers are showing their support for other storm victims by donating food, water, and other badly-needed supplies.

"It's hard," said Rick Campbell. "But it brings everybody closer, too. So, we're blessed, and we appreciate all the help right now."

Across southern Indiana, storm survivors were dealing with another challenge Monday - two-to-four inches of snow fell across the area overnight.
